如何找到 rollup 3.1.0 更新错误？

Question

1. 我想安装rollup-plugin-visualizer，但需要更新汇总。

2. 更新汇总从1.8.0到3.1.0

   出现错误

   [!] RollupError: Node tried to load your configuration file as CommonJS even though it is likely an ES module. To resolve this, change the extension of your configuration to ".mjs", set "type": "module" in your package.json file or pass the "--bundleConfigAsCjs" flag.
   

3. 删除node-modules文件夹和package-lock.json并再次安装npm i

出现错误

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

rollup-plugin-babelnpm 页面说！！！

该软件包已被弃用并且不再维护。请使用@rollup/plugin-babel。

4. 我已经删除rollup-plugin-babel然后安装@rollup/plugin-babel. 现在我收到此错误

[!] RollupError: Node tried to load your configuration file as CommonJS even though it is likely an ES module. To resolve this, change the extension of your configuration to ".mjs", set "type": "module" in your package.json file or pass the "--bundleConfigAsCjs" flag.
    Original error: Cannot use import statement outside a module

有人可以告诉我在哪里寻找这个错误的解决方案吗？

Answer 1

我已经找到解决方案了。首先将格式从 更改'esm'为'cjs'inrollup.config.js

export default {
    ...
    output: [
             {
                format: 'cjs',
                ...
            },
       
    ]
};

然后rollup.config.js改为rollup.config.mjs

你好，我在运行“npm run rollup”时遇到同样的问题

RollupError：Node 尝试将您的配置文件加载为 CommonJS，即使它可能是 ES 模块。要解决此问题，请将配置的扩展名更改为“.mjs”，在 package.json 文件中设置“type”：“module”或传递“--bundleConfigAsCjs”标志。
